Abstract: 1,007,732. Pit cage loading bridge. STAMICARBON N.V. June 25, 1962 [June 26, 1961], No. 24376/62. Heading B8E. A loading bridge 1 for a pit cage is hinged to the fixed floor 2. The bridge is raised to the inoperative position shown by fluid pressure acting in a piston and cylinder unit 5, 7 and is locked in this position by a locking device 8 operated by a cylinder 9. The bridge is allowed a controlled descent solely under gravity to the operative position when the cylinder by-pass 10, 11 is opened by a valve 12, pressure to the cylinder 7 being constantly supplied from a vessel 14. With no cage in position a valve 16 is open operating the cylinder 9 to lock the bridge in the raised position and to lock a valve 19 closed so that even operation of a manually controlled valve 23 cannot admit pressure to the line 13 of the valve 12. When a cage is in position a detector device operates a coil 18 to close the valve 16 so that the locking device 8 unlocks and the valve 19 can be opened when the valve 23 is operated so that pressure reaches the line 13 and opens the valve 12 in the by-pass 10, 11 so that the bridge can fall into operative position. Momentary opening of the valve 16 as a cage moves from deck to deck is insufficient to raise and lock the bridge.

Abstract: 317,400. Stout, H. H. Aug. 15, 1928, [Convention date]. Wire; rods.-In a process for refining and working copper the scrap metal is formed into briquettes, cleaned by hydrogen, water gas, &c. at a temperature below the melting point of the metal, and then extruded through a hollow plunger. The billets 17 produced from scrap copper in an hydraulic briquetting machine are fed into a gas-tight electric furnace 18 and subjected to the action of the cleaning gas entering by a pipe 20 and leaving by a pipe 21. The billets are moved through the furnace by a conveyer system and heated to about 1500‹ F. The cleaned billet is fed into another chamber in front of a plunger 23 which forces the billet into a chamber 22, an aperture block 28 being then forced by a plunger 25 against the billet, causing the latter to be extruded in wire or rod form. The plunger 25 is stopped before the entire billet has been extruded and a fresh billet fed into the chamber 22 forming with the stub of the previous billet a homogenous mass. Other gases such as nitrogen, steam carbon-dioxide and hydrocarbon gases may be used with the hydrogen or water gas. The Specification as open to inspection under Sect. 91 (3) (a) refers also to other metals such as zinc. This subject-matter does not appear in the Specification as accepted.

Title: A machine for cutting sheet materials
IPC: B26F1/40
Filed: 1964-06-15
Abstract: 1,032,993. Cutting-out presses. A. CHIESA, [trading as OFFICINA MECCANICA ARTORIGE CHIESA]. June 15, 1964 [Oct. 12, 1963; Dec. 6, 1963], No. 24717/64. Heading B4B. In a cutting-out press in which a beam 3 is moved downwardly to press a tool 6 through sheet material 5 supported by a table 2 by means of a piston 7 moving in a cylinder 8 to which hydraulic fluid is supplied, the downstroke of the beam is stopped and reversed by a control of the overpressure in the cylinder 8. The overpressure is measured and controlled by a pressure controller 34. The discharge from the cylinder 8 is controlled by a valve 15 operable by a solenoid 17. The solenoid and the pressure controller are included in an electronic circuit which comprises transistors 28 to 31, a transformer 21, 22, 25, resistances 35 to 47, flip-flops 48, 49, a stabilizer 50 and rectifiers 23, 51, 52. The beam 3 is fitted with push-buttons 32, 33. When a voltage is applied to the whole circuit transistors 30, 31 become non-conductive owing to the forced conductivity of transistor 29. To start the press, both push-buttons 32, 33 are depressed. The forced conductivity of transistor 29 is thus discontinued. At the same time, the transistors 28, 30 and 31 are made conductive, the solenoid 17 is energized and the valve 15 operated to cause the downstroke of the beam 3. At the end of the downstroke of the beam, an overpressure is built up in the hydraulic circuit which results in operation of the pressure controller to close contacts 12, 13. This causes transistor 29 to become conductive again while the transistors 30, 31 become non-conductive and the solenoid 17 is de-energized whereby the beam is stopped instantaneously and then reversed to its starting position under the action of spring 18. The above operation can be repeated after having opened, and again closed, the contacts of push-buttons 32, 33.
